Asteroids emulator for the Commodore 64

This isn’t the first emulator written for the Commodore 64, but nontheless: Norbert has released an Asteroids Emulator for the Commodore 64, emulating the original 1979 arcade game.

“The original program of the Atari arcade machine, which is 6502 based, is directly executed by the C64’s 6510 CPU. The graphics and sound hardware of the original machine is (more or less) exactly simulated by the C64 in software. The main challenge was (and a little bit still is) to accomplish an acceptable and constant speed.”
